Dashes of dark blue sparkle will accent your designs with the Swarovski 2058 SS20 XILION rose enhanced flatback in Crystal Blue Shade. These enhanced 2058 flatbacks display more facets than the 2028 flatbacks for the luminosity of a multi-layered cut and intensified color. The table is also smaller and higher, allowing more space for the facets to catch and reflect light. These crystals feature dark blue color that sparkles darkly with hints of grey light. Use an adhesive to attach these rhinestones to clothing, accessories and more! SS20 flatbacks are approximately 4.6 to 4.8mm in diameter.
